Abstract:

This slit pipe is provided with a hollow cylindrical pipe body (12), and connecting slits (14) that pass though from the outer surface to the inner surface of the pipe body (12), said slits (14) being provided in a helical configuration along the axial direction of the pipe body (12). A meshing unit (U) is provided repeatedly on the slits (14), said unit (U) comprising: a first base unit (u1); a first skewed part (u2) for forming a wedge shape by being folded back on the distal end side of the first base unit (u1), a second base unit (u3) for forming a wedge shape by being folded back on the distal end side of the distal end side of the first skewed part (u2), and a second skewed part (u4) for forming a wedge shape by being folded back on the distal end side of the distal end side of the first skewed part (u3).
